Durameter Metering Pumps
By Flow-Tech Industries
Durameter’s metering pumps provide customers with an exceptional design to ensure a long life of reliable metering. For more than 75 years, customers have selected Durameter to meet even their toughest requirements. Durameter pumps are built in accordance with API 675 specifications.
Durameter’s Evolution (EV) Series metering pumps include the EV1 Series and the EVA Series.
Designed to Adapt
The EV Series metering pumps are designed for maximum flexibility and greater control. As requirements change, modification of the EV pumps allows for changes to plunger diameters, liquid end materials or designs when pumping slurries, viscous or other challenging process fluids. For added convenience, the EV1 Series pumps easily convert from a simplex to a duplex configuration using the same pump frame or when connecting multiple frames to drive up to twelve heads using a single motor.
Designed for Simplicity and Cost-Effectiveness
The EV Series pumps employ a revolutionary modular design with four independent assemblies, or cartridges, that are independent and field convertible. This makes routine maintenance quick and easy and increases your savings by reducing downtime.
Designed to Assure Performance in Your Application
Durameter pumps are available with DURAmatic electronic stroke control for controlled processes. The DURAlert diaphragm performance option is available to assure diaphragm integrity even in the most critical service.
